forms and by the suppression of some genera that seem unnecessary. 

 The Psylloborini are included to avoid the division into so many 

 groups. The term " metacoxal plate " is used for that portion of the 

 first ventral segment included above the ventral lines visible on that 

 segment in this and following groups (see sketch of under side on 

 plate XIV). 



Body larger, antennae shorter with last joint truncate. 



First ventral lines arcuate, continuous, not quite entire, the metacoxal plates shorter 



than the segment ; body oval Adalia. 



First ventral lines curving outward to the sides of the body along the first suture, 

 the included area (or metacoxal plate) frequently divided by an oblique line ; 

 body usually rounded. 



Tarsal claws with a large subquadrate tooth at base Coccinelhr. 



Tarsal claws cleft within Neomysia. 



Body smaller; antennae slender with last joint elongate Psyllobora. 



Division of Coci iiulhe. 

 Metacoxal plates divided by an oblique line joining the bounding arc at about its 



middle point, forming an angulate inner plate I 



Metacoxal plates not or only partially divided, the oblique line obsolete or feeble... 2 



1. Oblique line meeting the bounding curve at middle of segment; elytra blue. 



Agrabia. 

 Oblique line meeting the bounding curve at hind margin of segment.. .Coccinella. 



2. Mesosternum truncate with a minute notch at middle Harmonia. 



Mesosternum broadly and deeply sinuate. 



Prosternal process narrow, strongly bicarinate Atlisocalvia. 



Prosternal process broad, strongly convex in a transverse direction and prominent 

 at the apical margin Anatis. 



To a large extent the markings of the thorax are uniform through- 

 out each genus and reference to the figures will save minute study 

 of the under surface which, as specimens are ordinarily mounted, is not 

 easy. 



Of the genera tabulated by Major Casey, Neoharmonia, Cycloneda 

 and Ol'a are included above with Coccinella — Neomysia replaces 

 Mysia of the check list. Cleis is included with Harmonia. 



Adalia Muh. 



Thorax with a broad M -shaped median black design, the broad pale margins immacu- 

 late bipunctata. 



Thorax with M -shaped design and a black point at the center of the broad yellow 

 margin frigida. 



Thorax with M-.shaped design and a submarginal black spot; elytra with transverse 

 series of spots or transverse bands annectans. 



Thorax black with narrow pale apical and lateral margins humeralis.
